assignment of cost centre

Hi

1.We have 4 machine each one has been defined as cost cenres individually.There is one G/L defined for consumption of raw material.Now the management wants the details of total raw material consumption machine wise& at the same time functional people wants the cost centre should be defaulted while passing the entry.now please suggest how to go about this issue.

2.Can multiple cost centre be assigned to one fund centre

Thanks
